Check com.radaee.util.PDFAESEnc, com.radaee.util.PDFAESStream and com.radaee.reader.PDFEncAct

For other algorithms you need to implement it yourself using PDFStream

Hi.
I've reviewed the com.radaee.util.PDFAESStream file. As far as I understand, this class supports random access to decrypted input stream. Is it really can to do 'seek over decrypted stream' operation in backward direction as well as in forward?
